President Biden reveals the first full-colour image \u2013 the deepest infrared picture of the Universe yet \u2013 to a waiting world<\/figcaption><\/figure>\n\n

After decades of <\/strong>waiting, the James Webb Space Telescope (JWST) has released its first scientific images to the public. <\/p>\n\n

\u201cToday, we present humanity with a ground-breaking new view of the cosmos \u2013 aview the world has never seen before,\u201d said NASA administrator Bill Nelson. <\/p>\n\n

On 11 July, President Joe Biden was given an advance view of the images, and thanked \u201cthe team at NASA for once again showing who we are\u201d. <\/p>\n\n

The first deep-field image was released that evening. The next day, on 12 July, NASA released three more images, as well as a spectra of exoplanet WASP-96b\u2019s atmosphere, which showed clear signs of water. Before long, the images were shared on news channels and social media the world over, as people marvelled at the unprecedented detail in the images \u2013 all of which were taken within a single week of observing time.<\/span><\/p>\n\n

\u201cThe Hubble Deep Field was two weeks of continuous work with Hubble. We did [ours] before breakfast,\u201d says Jane Rigby, operational project scientist for JWST. \u201cThe amazing thing about Webb is the speed with which we can churn out discoveries.\u201d <\/p>\n\n

But while the images stunned the world, a report on JWST\u2019s performance revealed an unexpectedly large micrometorite strike in May has caused a \u201csignificant uncorrectable change\u201d to one of the mirror segments. Fortunately it only affects a small area and JWST is still performing above expectations. <\/p>\n\n

I was wrong. Utterly, wonderfully wrong. For over a decade, I\u2019ve flinched when space agency press releases described JWST as the successor to the Hubble Space Telescope. Though both are incredible tools for science, Hubble is best known for its spectacular images. JWST, though, is an infrared telescope; working with wavelengths beyond what our eyes can see inevitably makes the view blurrier. Setting up JWST as a machine capable of producing images as beautiful as Hubble\u2019s, no matter their scientific utility, was asking for disappointment. <\/p>\n\n

Wrong, as I said. I have the JWST image of the Carina Nebula as my laptop background, and Stephan\u2019s Quintet on my phone. It turns out that a mirror six metres across is large \u2013 large enough to produce crystal-clear, pin-pricksharp images to wow the world.<\/span>

Welcome to the infrared Universe! Beautiful, isn\u2019t it?<\/p>\n\n
